It mentioned the "extended processor unit interface"
to Z8000 cpu with a 6 page chapter. some reversed
instructions can be used as EPU instructions. It said
an EPU can be a floating point processor, a graphics
processor, a network processor.... It described the
EPU hardware interface but didn't say more about a
floating point processor. If you have interest I can
mail you a copy.
